-  * @brief   CRC HAL module driver.
-  *          This file provides firmware functions to manage the following 
-  *          functionalities of the Cyclic Redundancy Check (CRC) peripheral:
-  *           + Initialization and de-initialization functions
-  *           + Peripheral Control functions 
-  *           + Peripheral State functions

-                     ##### How to use this driver #####
-  ==============================================================================
-    [..]
-      The CRC HAL driver can be used as follows:
-
-      (#) Enable CRC AHB clock using __CRC_CLK_ENABLE();
-
-      (#) Use HAL_CRC_Accumulate() function to compute the CRC value of 
-          a 32-bit data buffer using combination of the previous CRC value
-          and the new one.
-
-      (#) Use HAL_CRC_Calculate() function to compute the CRC Value of 
-          a new 32-bit data buffer. This function resets the CRC computation  
-          unit before starting the computation to avoid getting wrong CRC values.
